Specification of Letters Patent.

Patented sept. 29, 1908.

Application filed August 17, 1907. Serial No. 389,079.

To all whom it may concern.'

Be it known that I, SAMUEL'R. S'rINE,

-residing at McVeytown, in the county of Mifflin and State of Pennsylvania, have invented certain new and useful Improvements in Ranges, of which the following is a speciication.

This invention seeks to provide an improved construction of stove or range of that j type designed for establishing a hot-water heating system adequate for furnishing hot water for radiators or other heat distributing means located` in the various apartments of the dwelling. Y

The primary object of my present invention is to provide a cooking range capable of being utilized for the ordinary purposes for which a kitchen range is provided, and in which the water heating means is coperatively so combined with the fire box and the smoke or combustion flue, whereby a continuous heating of the water under a substantially maximumV heat radiation from the fire box and smoke flue is maintained, irrespectiveof the adjustment of the drafts for regulating the heat current directly to the off-take or smoke flue or around the oven.

My invention also comprehends an improved construction of hollow framing that constitutes the opposite sides of the lire box, the manner of connecting the said framing, and an improved arrangement of a series of supplemental water circulating tubes mounted within the smoke or combustion flue of the range.

In its more subordinate features, my invention consists 1n certain details of construction, peculiar combination of parts, all of which will be first described `in detail and then be specifically pointed out in the appended claims, and illustrated inthe accompanying drawings, in which:

Figure 1, is a perspective view of a kitchen range in which is embodied my invention. Fig. 2, is a partial longitudinal section thereof on the line 22 of Fig. l. Fig. 8, is a detail perspective view that illustrates the inner hollow casting that forms the inner side of the lire box, the supplemental circulating tubes and chamber,the oven portion of the range being also shown. Fig. 4L, is a transverse sectionl taken centrally on Fig. l.

vIn the practical application of my present invention, the body or oven portion of the range may be of any well known construction in which the oven 4 is surrounded at the top, bottom and sides by hot air spaces Qthat discharge into the smoke outlet or offtake iiue 3, which in the ordinary construction, extend some distance above the stove top, as indicated by 30, and perform the usual function of warming the baking cham- 1 ber fl, and for another reason, presently explained.

It should be here stated, that my present invention in its generic nature, embodies some of the features disclosed in my Patent #717,047, granted December 30, 1902, in ,which is disclosed a hollow header for the 1 fire-box, with which the water inlet and outlet pipes connect, and which also joins with a water box within the fire-box or chamber.

In my present` construction, I dispense -with thehollow header at the rear end of the fire-box, as shown in my patent hereinvbefore referred to, but I form the opposite lsides of the fire-box of hollow rectangular `castings or frame which are designated respectively, 5 and 6, in the drawing, the outer one 5, of which forms the solid front wall 50 of the fire-box and is hollow its full length, whereby to create a water-jacket or space 5l `the full height of the stove front, as best shown in Fig. 2, by reference to which it will .be also observed that the inner wall of the tire-box is in the nature of a hollow rectangu- A`lar frame 6 having the height of the opposite side frame 5. The said frames 5 and 6 extend parallel t0 each other, and have their `front ends connected in any suitable manner, with the front plate 8 of the range, and the rear ends of the said hollow frames 5 and 6 are joined by feed laterals or pipe sections 9-.9a that respectively screw into the lower rear ends of the said hollow frames 6 and 7, and are joined by a T or union coupling 9b, with which the water feed pipe l() connects in a manner, best shown in Fig. 3, such connection of the water pipes 9 and 9a with the hollow castings or frames forming a convenient means for sustaining the rear ends of the said frames in proper correlative position, it being understood that the rear end of the fire-box is closed by a back plate 11, also screwed to the side frames 5 and 6 in any approved manner.

The hollow rectangular frames 5 andv 6 are also provided with supporting ledges, for sustaining the grate 13, which may be of any approved construction, a simple form of grate being illustrated in the drawings, it

being understood that the fro'nt plate or wall of the range has the usual front draft andV feed door 14, and the ash-pit door 15.

lVhil'e I have not shown it, it is obvious that when a range is equipped with a rotary or dumping grate, that the axle of the grate is projected to the front of the range to be engaged by the grate adjusting handle, in any well known manner.

So far as described, it is obvious that by reason of making the outer or front wall of the box hollow, from the top to the bottom, I obtain the maximum heat volume against the said wall for heating the water that circulates within the said wall at all times, irrespective of the adjustment of the dainpers of the stove for detlecting the heat and products of combustion in the direction designated, and since the inner frame of the firebox is also in the nature of a hollow casting, which casting is in communication with the front water back section, it follows that a circulation of water is passed entirely around the sides and also over the iear end of the lire-box as well as around the sides of the ash-pit.

To further provide for maintaining a positive heating of the water and also for utilizing the waste or off-take heat products of a. range, I form the inner frame with a vertical extension or supplemental water circulating compartment that is so positioned relatively to the off-take Hue of the range, as to project upwardly therein to a point near the warming shelf and to still further provide for heating the water, I tit the said supplemental chamber 70 with detachable water tubes 71, which are preferably of copper, so as to obtain the greatest heating radiation. These tubes 71 project into the o-take flue and in the vertical path of the discharge of the products of combustion and to still further provide for obtaining the maximum heat radiation, as the hot air and products of combustion pass up to the smoke flue, the several copper tubes '71 are staggeredly arranged as shown.

015a designates the outlet pipe which communicates with the top of the supplemental water heating chamber, which pipe, in practice, is carried up toward the ceiling and suitably coupled with radiators or other means of distributing heat under what is known as the hot-water system 7.

By reason of the peculiar construction and cooperative ariL ngement of the several parts as shown and described, the rectangular frame sections 5 and 6 can be readily made so as to be applicable to right or left hand arrangements of ranges and furthermore by reason of the means employed for connecting the said section, they can be also readily used in combination with sheet steel or cast metal ranges as may be desired. A

The outer rear ends of the hollow side frames' are also braced and joined by one or more pipes 17 that have right and left'. threads at the ends for engaging the threaded apertures in the hollow members 5 and t5.-

It will be apparent by referring particularly to Fig. 2, that while I have provided for circulating the water at the inner side of the tire-box and the ash-pit, since the inner wall of the ash-pit and tire-box is in the nature of a rectangular hollow body, the regular draft qualities of the stove are not effected, since the products of combustion can freely pass out through the rectangular side frame, up over direct to the off-take or under and around the oven indirectly to the k off-take according to the set of the ordinary stove dampers (not shown).

Detachable tubes 7l are also secured to the rear end of the frame (i from the bottom to the top for providing increased water circulation, and these tubes 71 project into the lower end of the off-take line, as will be learly understood by reference to Figs. 'l and t of the drawings.

Among other advantages, it should he stated, that my improvements are of such character that they may be combined with the ordinary type of oven found in almost every form or style of kitchen range, since the particular construction of hollow framt` and its relation to the oven is such that the efficient heating of the oven is not interfered with, thus making it possible for manufacturers of ranges adapting my improvements for their particular style or st yles of ranges without materially modifying their special arrangement and with but little additional expense in construction.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is,-

1. In a cooking range; a tire box comprising closed ends, a hollow outer wall, an inner wall formed of a rectangular hollow frame comprising hollow bottom and top members connected by hollow vertical members, pipe connections that join the inner and outer walls, a feed pipe that joins with one of said pipe connections, and a distributing pipe connected with the hollow rectangular frame for the purposes specified.
